PAPER-FILE.

$PECIFICATION forming part of Letters Patent No. 371,547, dated October 18, 1887. Application filed June 1. i887. Serial No. 239,986. (No model.)

To aZZ whom it may concern:

Be it known that I, CALVIN ALGERNON CAMPBELL, of the city of Montreal, in the county of Hochelaga, in the Province of Quebec, Canada, agent, have invented certain new and useful Improvements in Paper-Files, of which the following is a specification.

The invention relates to that class of paperfiles in which the transferring-wires are arched and look at their points with the receivingwires, so that the paper may be readily moved from the receiving-wires onto the transferringwires; and the objects of my invention are, first, to so arrange the receiving and transferring wires that they shall remain rigidly and permanently in position, even when their points are moved apart for the purpose of permitting the removal of the paper; secondly, to connect the index-cover to the wires, so that it may be thrown clear of the receiving-wires without being moved out of place on the transferring-wires, and, thirdly, to provide an improved device for locking the index cover.

My invention consists, essentially, first, in adapting mechanism by which the points of the receiving-wires are moved toward or from the points of the transferring-wires5 secondly, in hinging the index-cover to a plafe fitted over the transferring-wires and making slots in the index-cover, so that the said index cover shall be thrown off the receiving-wires without raising its hinged end; and, thirdly, in adjustably connecting to the index-cover a plate having tapered slots made in it to fit over the receiving-wires.

Figure l is a perspective view of my improved paper-file. Fig. 2 is an enlarged perspective detail, partially in section, of my receiving and transferring wires with the mech anism for operating the receiving-wires. Fig.

3 is an alternative form of the mechanism shown in Fig. 2.

In the drawings like letters of reference indicate corresponding parts in the different figures.

A are the receiving-wires, and B the transferring-wires. \Vhen I make the transferringwires in pairs, I form them both out of a single piece of wire, as indicated in Fig. 2, and in any case I rigidly attach them to the bed-plate O, which is fastened to the bottom board, D, of the file.

\Vhen the receivingwires are made as shown in Figs. 1 and 3, the said receivingwircs are fastened to the top E of the bedplate, as indicated. \Vhen made in this form, the points of the receiving-wires are separated a snfficient distance from the points of the transferring wires to allow papers to be placed on or removed from the file, and as it is necessary that the space thus left between the points of the wires referred to shall be closed or filled up when the papers are to be. moved from the receiving-wires onto the transferringwires I make the receiving-wires hollow and pass through each receiving-wire a smaller wire, F, which I connect by a lever, G, to the rod H, which I journal in the bed-plate O and provide with .a suitable handle or crank, I, located either in the position indicated in Fig. l or in any other convenient place.

When the two receiving-wires are used, I connect them together by the horizontal rod J and provide two levers G. Thus itwill be seen that in order to open or close the space between the point of the receivingwire and the point of the transferring-wire it is merely necessary to adjust the crank-handle I so as to move the wires F in the direction desired.

A spring, K, attached to the bed plate 0, is arranged to act on the rod H, as indicated in Fig. 2, so that the said spring will hold the wires F either against the points of the transferring-wires or below the points of the receiving-wires, accordingly as they may be ad iusted by the movement of the crank I.

In Fig. 2 the receiving-wires A are connected direct to the rod J, and adjustablysupport them in sockets L, attached to the bedplate 0, so that the receiving-wires themselves may be adjusted for the same purpose as the wires F. Instead of the socket L, I sometimes steady the receivingwires A, when made as shown in Fig. 2, by a smaller wire inserted into the hollow receiving-wires A. and rigidly fastened to the top E.

As shown in Fig. 3, the top E is made so that it may be removed from the bed-plate O, and in order that the receiving'wires may be moved with iivI form a fork on the end of the lever G, as indicated.

Vliill the view of locking the top E in position I attach a projecting finger or fingers, b, to the side of the bed-plate O, and on the hottom of the top E, I attach a finger, d, bent so that it may be slipped below the finger b when the top E is placed in position, and in order to lock the said top I attach to it the sliding latch 6, formed so that one portion of it will project below the stationary part of the top 0 the bed-plate O. I

It will be noticed that the index-cover M is hinged to the plate N, which is pierced, so that it will fit over the transferringwires B. It will also be seen that slots 9 are made in the index-cover M, so that thesaid cover may be thrown back over the transferring-wires without moving the plate N.

In Fig. l I show my lock for securing the index-cover in position. This lock consists of a plate, 0, adjustably connected to the cover M, and having tapered slots It made in it, so as to fit onto the receiving-wires A, the said slots being tapered, so that they will grip the receiving-wires A when the plate 0 is adjusted in the direction required.

It will of course be understood that the plate N may be made in two-parts when used with a double-arched file; or, in other words, lugs with holes in them to fit over the transferringwires may be hinged to the index-cover,which I consider as an equivalent for the plate N which I have shown.

Among the advantages of my invention I may mention that by making the receivingwires vertically adjustable I am enabled to utilize them for the purpose of punching holes in the papers to be filed. In order to accomplish this'end, I have merely to make punches at the points of either the receiving-wires or the transferring-wires, suitable gages being provided, if desired, for the purpose of guiding the paper in proper position between the points of the receiving and transferring wires. By hinging the indexcover to a plate or lug fitting over the transferring -wires and by making the slots 9 the'index-cover has merely to be thrown back, where it will remain, leaving both hands of the party using the file free to handle the papers.

I am aware that it has been proposed .to g

construct a letter-file wherein the transferringwires were so connected to mechanism that when it was desired to file any papers thereon 1. -In' a letter-file, a rigid arched transferring-wire, combined with a wire moving in a vertical guide, and mechanism for imparting to said wire a vertical movement upward to close the space between the adjacent ends of said wires, asset forth.

2.-In a Ietter-fiIe an arched transferringwire, in combination with a receiving-wire vertically adjustable and connected by the lever G to the rod H, journaled in the bedplate 0, arranged substantially as and for the purpose specified.

3. In a letter-file, a pair of arched transferring-wires formed in one piece and rigidly fastened to the bed-plate G, in combination with the vertically-adjustable receiving-wires A, connected to the rod H by the lever G, substantially as and for the purpose specified.

4. An indexcover, M, having slots 9 made in it to fit over the receiving-wires A, in combination with a plate, N, fitted over one end of said cover, hinged to the index-cover M and fitted over the transferringwires B, substantiallyas and for the purpose specified.

5. The'combination, with receiving-wires, of a plate,,0, lengthwise adj ustably connected to the index-cover M, and having tapered slots h to fit over the'receiving-wires. substantially as and for the purpose specified.
